Lateral insertion method for spinous process spacer with deployable member
First Claim
Patent Images
1. A method for laterally implanting an apparatus between spinous processes including the steps of:
- accessing spinous processes from the side;
inserting between the spinous processes at least one arm of the apparatus with the arm in an insertion position; and
after the apparatus is inserted between the spinous processes, deploying the arm to a retention position relative to a side of the spinous processes.

Abstract
A spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy by expanding the volume in the spine canal and/or neural foramen. The implant provides a deployable second arm that converts between a first position for insertion and a second position for retention of the implant between adjacent spinous processes. A tool can be used to insert the spine distraction implant.

7. A method for laterally implanting an apparatus between spinous processes including the steps of:
-
accessing spinous processes from the side;
inserting between the spinous processes first and second arms of the apparatus with the arm in an insertion position and with the first and second arms positioned adjacent to each other; and
after the apparatus is inserted between the spinous processes, deploying the first and second arms to retention positions relative to a side of a first spinous processes and a side of a second spinous process respectively, wherein in the deployed position the first arm and the second arm are positioned away from each other. - View Dependent Claims (8, 9, 10, 11, 13)

14. A method for laterally implanting an apparatus between spinous processes including the steps of:
-
accessing spinous processes from the side;
inserting between the spinous processes at least one arm of the apparatus with the arm in an insertion position and wherein the insertion position is parallel to an axis that is through a space between the spinous processes and about perpendicular to a plane that contains the spinous processes; and
after the apparatus is inserted between the spinous processes, deploying the arm to a retention position relative to a side of a spinous processes, wherein the retention position is in a plane that is about parallel to the plane that contains the spinous processes. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method for laterally implanting an apparatus between adjacent spinous processes, the apparatus including a first arm at a first end of a spacer and a second arm at a second end of the spacer, the method comprising the steps of:
-
accessing spinous processes from the side;
inserting between the spinous processes the first arm of the apparatus with the arm in an insertion position; and
after the apparatus is inserted between the spinous processes, deploying the first arm to a retention position relative to a side of a spinous processes and deploying the second arm to a retention position relative to a side of a spinous process. - View Dependent Claims (21, 22)
